First and foremost, this has nothing to do with Mars or the Moon being the same size or any of that sort of malarkey. This is a real event that will take place early Tuesday morning. A lunar eclipse happens when the Moon passes through the shadow of the earth. Reflected light given off from the moon is scattered by the Earth’s atmosphere and often the moon will appear reddish or orange. It’s a little early in the morning but we should have a clear sky for the show. Happy viewing!
